Oclaro (OCLR) -6.8% AH after warning it expects FQ1 (Sep. quarter) revenue of $149M, below a $162.2M consensus. Oclaro, which closed its acquisition of Opnext on July 23, blames weak market conditions, a slower-than-expected recovery of share lost thanks to Thai flooding, and a slow ramp of new products, including costlier 40G and 100G parts. Might the Opnext deal also be prompting customers to diversify? Optical component rivals JDSU, FNSR, OPLK, and NPTN could fall in sympathy.
